Press quenching is a specialized quenching technique that can be utilized during heat treatment to minimize distortion of complex geometrical components by using specialized tooling for generating concentrated forces that constrain the movement of the component in a carefully controlled manner. This article provides a detailed account of the fundamental components of quenching machines, including the upright machine section, control panel, lower die table, tooling, and the base. In addition, it summarizes the critical factors affecting component distortion during press-quenching.
